MACHINE FOR BREASTING HEELS.

Specification of Letters Patent.

Patented Apr. 26, 1910.

Application filed July 10, 1906. Serial No. 325,516.

To all whom it may concern:

Be it known that I, JOSEPH GOULDBOURN, a subject of the King of England, residing at Leicester, in the county of Leicester, England, have invented certain Improvements in Machines for Breasting Heels, of which the following description, in connection with the accompanying drawings, is a specification.

like reference characters on the drawings indicating like parts in the several figures This invention relates to machines for breasting heels.

In the manufacture of boots and shoes it is desired to trim the breasts of heels to contours which vary according to different circumstances, such as the style or the height of the heel.

The principal object of the present invention is to provide a machine permitting breasts of heels to be trimmed to various contours, said machine being so constructed as to secure by its adjustment such variation as may be desired.

A machine embodying my invention allows various contours to be produced without the employment of interchangeable parts, such as guide templets, cams, or cutters of various sizes.

The embodiment of the invention herein shown by way of example is arranged to permit variation in the contour of the line in which the breast and tread of a heel meet and is, moreover, adapted for trimming heels before they are secured to boots or shoes. It will be understood, however, that machines embodying my invention may be arranged to permit variation in contour-of the line in which the breast and side of the heel meet or the construction may be such that heels may be trimmed after being secured to boots or shoes.

An important feature of the invention "consists in the provision of a cutter and a supporting memberare arranged for relative movement, and mechanism is provided contour of the heel breast produced may be p of different degrees of concavity or convexity or may, if desired, be straight. The controlling mechanism may be arranged to control also the relative movement of the cutter and work into and out of cut. The rela-' tion chosen between the cutter or the work support and the controlling mechanism may. at times be such that the work is out of or too far within the range of the cutter, and the present invention accordingly includes means for shifting the cutter relatively to the work while maintaining unaltered the relation of the work or the cutter to said controlling mechanism. Provision is thus made for varying the depth of the out either from time to time or during the treatment of a single breast. According to a convenient construction one of said members is adjustably sustained upon a movable controlling device, the other member being mounted in stationary position. The controlling device is adjustable with relation to the stationary member in order to vary the path of the member sustained upon said device. The parts are so connected that adjustment of a member upon said device and of'the device itself may be simultaneously made. Where said adjustments are simultaneously made mechanism is preferably provided for independently adjusting the relations between the cutter and the heel in order to vary the depth of the cut.

I have shown herein two embodiments of the invention in one of which the cutter is stationary and the work is moved into contact therewith and in the other of which the cutter is arranged for movement and the work is stationary. The cutter employed is a rotary cutter and the work support shown is arranged topermit a heel to be held in operative relation to the cutter. In the embodiment of the invention in which the cutter is stationary the parts are so arranged that in the operation of the machine the heel is moved about the periphery of the cutter and is simultaneous a predetermined degree sothat the heel is trimmed to a predetermined contour difie'r ing from that of the cutter. Where the cut ter is arranged for movement the'parts are arranged to cause the center of the cutter to move in a predetermined path from side to side of the heel.

Fig. 6; Fig. 8 is a sectional view of the cutter, member or plate, and adjacentparts on the line 8-8 0 Fig, 6; Fig. 9 is a sectional detail on the line 99 of Fig. 6.

\ Referring first to F igs. 1 to 5, a rotary cutter l is secured to a shaft journaled in the main frame2 of the machine and rotated by any usual means. A lug 4 (Fig. projects from the mainframe 2 and mounted upon it is a bracket 6 upon which is fulcrumed at 8 an arm 10. The arm 10 may be han e 12 that is supported on the bracket 10. A slide 16 is adjustably mounted in guideways 18 (Fig. 4) in the arm 10 and i carries two rollers 20, 22 (Fig. 5) mounted upon studs 24, 26, each roller extend' into one of two cam grooves 28, 30 forms in a controlling member or plate 32 movably su ported by said rollers and studs on the slide 16 .and formed with a handle 33. A clam ing handle 34 is provided to retain the sli e .16 in adjusted position.

Movably mounted upon the controlling plate 32 is a heel carrier 36 upon which a heel 38 is adapted to be held by means of a suitable clamp 40 pivoted, at 42 to the cary rocked to rier 36 and having its free end adapted to bear,l )yway of a contact piece 46; upon the seat of the heel, the top-lift of the latter resting upon the carrier 36. To operate the clamp an adjustable link 48 is connected toit at 50 and is also connected at 52 (Fig. 3) to a lever 54 pivoted at56 to the carrier 36. Pivotally connected to the lever 54 is a rod 58 that extends through a hole in the carrier and also through a long straight slot 60 formed in the controllin plate 32 to permit adjustment of the carrier on the plate as-hereinafter described. A s iral cam piece 62 is rigidly attached to thev ower end of the rod 58 and a loose washer 64 ends.

loose spiral cam piece 66, providedwith ahandle 68, are interposed between the cam piece 62 and the controlling plate 32. A

movement of the handle 68, therefore, will 62, 66 andlever 54 cause the link 48. and clamp 40 to be depressed and thereby not.

the interaction of the spiral cam pieces only clamp the heel upon the carrier 36, but also clamp the latter to the controlling plate 32. A spring 70 is providedto elevate the clamp 40 when thehandle 68 is moved reversely. To position the heel upon the carrier there may be suitable interchan eable recessed plates 72 to. receive and 1 position the top lift.

I The operation of the parts as thus far described is as follows :-The heel having.

been clamped to the carrier 36 and the latter' simultaneously clamped to the controlling plate 32 in Fig. 1, the operator, by means of the handle 33 on the plate, moves the plate in the path in'whichit is guided'by the cam grooves 28, 30 in conjunction with the rollers 20, 22 aforesaid. The groove 30 is a straight slot,

the position thereon shown inwhile the other groove 28 is a longer slot comprising two portions a and 6. These cam grooves first allow the heel to advance toward the cutter 1 so that when the junction between the portions a and b of the groove 28 reaches the roller 20 on the stud 24 the breast of the heel is brought into close proximity tothe cutter A continued movement of the plate by the operator now causes the portion a of the groove 28 to travel along past the roller 20 and the groove 30 to reverse its direction of motion on the roller.22. This action of the cam grooves and rollers so guides the plate32 that the heel moves in a curved path past the cutter slightly rocking or rotating rela-. tively thereto and is trimmed thei'eby to a curvature which is difi'erent from that of the acting face of the cutter. If it be desired to trim the breast to a smaller curvature, that is to say, one nearer approaching a straight line, it is only necessary in the shown in Fig.1 to a position in which it is pinion 82 on a second shaft 84 on the nearer to the cam grooves 28, 30, and as this may move the heel too far within the range of the cutter, also to adjust the cutter slightly away from the heel or what amounts to the same thing, to adjust the controlling plate 32 and carrier 36 together forwardly in the machine. To this end the following mechanism is provided :The arm 10 has an extension upon which rack teeth 74 are formed. Engaging with these rack teeth is a pinion 76 on a shaft 78 journaled in the controlling plate 32 and "provided with an operating handle 80. An intermediate ate 32 gears with a second pinion 86 fixe on the shaft 78 and also meshes with a rack bar 88 attached to the heel carrier 36. To adjust the parts as described, it is only necessary, therefore, to unclamp the carrier 36 from the controlling plate 32 and the slide 16 from the arm 10 and then to turn the o erating handle 80 and thereby move tie carrier 36 on the late 32 toward the cam grooves 28, 30 an the carrier 36, plate 32 and slide 16 in company toward the front of the machine, and finally to re-clamp the carrier and slide in their new positions With the parts as re adjusted it will be found that during the breasting operation the heel will rock relatively to the cutter through a greater angle while it is in engagement with the cutter than it did before, and thereby more material will be trimmed from the sides of the breast which consequently will have a curvature more nearly approaching a straight line.

Fig. 5 is a diagrammatic view of the controlling plate 32 but showing the side thereof opposite to that seen in Fig. 1. Of the three diagrams comprising this figure that indicated in 'dotted lines shows the relative position of the controlling late 32, the heel 38, and the cutter 1 at the eginning of the breasting operation, while those indicated in full and chain lines show, respectively, the positions of the parts at the middle and end of the breasting operation. When the controlling plate, the cutter 1, and the heel are adjusted into the relative positions shown on each of the, diagrams comprising Fig. 5 the breast of the heel will be trimme straight, that is to say, the line forming the junction between the tread face and breast edge of the to lift or the corresponding face and edge of any" f'the oth'er lifts of the heel will be a straight line.

It will be understood that if a curvature equaling that of the cutter face be required for the breast of the heel or if a convex curvature be desired, the parts can be adjusted into positions in which such desired curvatures can be obtained.

- Preferably the parts are so arranged that the amount of material trimmed from the center of the breast is the same in all of the above described adjustments, that is to say, the thickness at the center line of the heel will be constant even though'the breast be concave, flat, or convex.

Provision is made, according to the present invention, for'readily interrupting and remaking the operative connections between the carrier on the controlling member and the devices by which said member is controlled, in order that the relationship that existed prior to the interruption between said two elements may be readily varied to alter the relative position of the heel and cutter and thereby vary the depth of out. In the embodiment of the invention illustrated in Figs. 1 and 2 the chain of connections between the carrier 36 and the slide 16 can, be interrupted by lifting the plate 32 and thereby moving the pinion 76 and rack teeth 74 out of engagement. The carrier 36 may then be adjusted upon the plate 32 without altering the position of the slide 16. A set screw 90 is provided for locking the carrier 36 in its adjusted position.

Referring now to Figs. 6 to 9 of the drawin s, in the construction illustrated therein a eel carrier 92 is mounted directly upon the machine frame 93 and a rotary cutter 94 is carried by a controlling plate 96 provided with a handle 98 by means of which it may be moved by the operator to bring the cutter into engagement with and to cause it to travel past the heel 100 to effect the breasting of the same. The path of motion traversed by the cutter is controlled by two rollers 102, 104, mounted upon studs 106, '108 screwed into the controlling plate, which rollers engage respectively with two cam rooves 110, 112 formed in the machine rame. To retain the controlling plate in position on the machine frame it has three lugs 114 which engage respectively with surfaces 116 and overhanging flanges 118 formed upon the machine frame 93.

With the parts adjusted as shown, the operation of the machine is as follows:lhe handle 98 is moved downwardly causing the controlling plate 96 first to swing about the roller 104 on the stud 108 as a center while the roller 102 on the stud 106 is traveling along the curved part (5 of the cam groove 110 thus bringing the .cutter into on age ment with the cornerof the breast 0% the heel. A continued downward movement of the handle 98 next causes the rollers to travel along the grooves 110, 112 and thereby so guide the controlling plate that the center of the cutter travels in substantially a straight line and consequently the cutter is caused to breast the heel with a straight out. When it is desired to give a concave curvature to the breast of the heel the cutter is adjusted to a position on the controlling plate 96 nearer to the grooves 110, 11.2 than that in which it is shown in Fig. 6. But

this adjustment of the cutter will necessitate ments may be readily obtained bothcutter and heel carrier are adjustably mounted upon the parts that support them. The heel carrier 92, which is. provided with a heelclamp similar to that described in connection with the construction illustrated in Figs. 1 to 5, is mounted in guideways 120 on the machine frame and is provided with an adjusting device 122 comprising a screw engaging a screw-threaded lug on themachine and connected to the carrier by a pin and oove connection. The cutter is secured to a shaft 124 carried in bearings on a slide 126- mounted in guideways in the controlling plate 96.

An adjusting device 128, similar to the device 122, is provided toenable the'slide 126 and cutter 94 to be adjusted on the controlling plate. The cutter is driven from any suitable source of power by a beltextending over a pulley 132 fast upon the shaft 124, any usual belt-tightening device being em loyed to obtain t e desired tension of t e belt on the pulley 132 during the movement of the cutter.

It will be understood that if it is desired to impart a convex curvature to the breast of the heel the cutter 94 will be adjusted to a position farther from the grooves 110, 112 than that in which it is shown in Fig. 6.

The .,path. of relative motion of, the heel.-v carrying member and the cutter-carrying member obviously may be controlled by cam slots other than those shownfor instance,

three slots of a similar shape to the lugs 114, Fig. 6-; but to enable the heel to be breasted to any curvature from that of the cutter to a straight line or even a convex curvature these slots must be arranged so that two pointsfor example, 106, 108-on the cutter-carrying member describe paths 110, 112

relatively to the heel-carrying member,

which paths are straight and angularly dis posed to each other or are non-concentric.
